WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 274,140, dated March'QQ, 1883. Application filed May 31,1882. (ModeL) To all whom at may concern:

Be it known that LFERDINAND PoLLMILL- ER, of. Eddyville, in the county of Wapello and State of- Iowa, have invented a new and Improved Washing-Machine, of which the following is a full, clear, and exact description.

This invention relates to a cylindrical rubher with ribbed surface, arranged on journals in a wash-tub, together with a stationary concave rubber of ribbed or roller surface, located beneath the cylindrical rubber, together with apparatus for working the cylindrical rubber forward and back ward, and so as to gain alittle one way until the clothes are nearly passed through between the two rubbers, and then gain similarly in the other direction to work the clothes back again, the said apparatus being operated by means of a fly-wheel to which thepower is applied by hand or foot, if preferred, as hereinafter described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation Ofll] y improved \vashingmachine. Fig. 2.is a plan view; and Fig. 3 is a longitudinal sectional elevation of the tub and the rubbing device.

A represents a rectangular 'tub,ot wood, set upon legs B, and a sheet-metal bottom, c,with a concave part, D, midway between the ends of the tub. j

E represent aseries of small rollers, arranged side by side, with their ends pivoted in the housings F, forming a stationary concave rubber, said rollersbein g in a curved line a little above the concave part D of the bottom of the tub, with a concave perforated plate of thin sheetmetal,G,located between them and said 'bottom D and attached to the lower edges of housings F.

H represents the fluted or ribbed cylindrical rubber,located over the stationary rubber and concentrically to it, being mounted on journals I J, thathave hearings in deep notches in the sides the tub, in which caps K are fitted over the journals, said caps beingfastened by screwsvz to be removable to allow the rub- ,bet to be removed from time to time for cleanin g the machine and for repairs.

The housings F are suspended by rods L and springs M from bearers N, attached. to the sides of the tub, over the journals of the cylindrical rubber and inside of said tub, for pressing the stationary rubber upward to cause the required pressure of the clothes between the two rubbers. The stud-pins P, attached to the sides of the tub and projecting through slots in the housings, are to prevent said housings and stationary rubber from being shifted sidewise under the action of rubber H.

The bearers N are detachably connected to the sides of the tub by screws 0, to allow of the removal of the rubbers when required.

The perforated plate Gr forms a connection of housings F that is required for keeping the rollers E in their bearings in said housings when removed from the tub, and it also forms a guard to prevent the clothes from getting 7 under the rollers. The perforations allow free To enable the rubcirculation of the water. ber H to be oscillated for rubbin g the clothes, it is provided with a ratchet-wheel, Q, upon one of its journals projecting out of one side of the tub, to which a pawl, R, is applied for turningit to the right, said pawl beingjointed toa bar, S, I

thatis pivoted on the journal J. There is also a pawl,T, applied to said ratchet for turning it to the left, said pawl being jointed to a bar, U, thatis also pivoted on the j ourn al J of the rubber H. These pawls are connected by rods W to the rock-lever X, on opposite sides of itspivot Y, so

that when one pawl advances the other retreats withrespectto theratchet. Therock-leverXis connected by a rod with the crank pin b of the lily-wheel d, to which the power is applied for working the rubber H. The IOCk-i6\ or X has 7 a slot, 0, for its pivot Y, and said lever X has a shifting-bar, f, connected with it for shitting along on pivot Y to one side or the other of the center between rods W, for shortening the throw of one of the pawls RT and lengthening the throw of the other, according to which way it is desired that the rubber H shall have the greatest movement to cause the clothes to gain in one direction, although the rubber 11 works forward and backward, the object being to have the clothes enter between the rollers at one side and gradually work through or nearly through to the other side, then back again, and repeating as many times as desired, the changes being eti'ected simply by shifting the rock-le- 2 t mnio ver on its pivot Y first one way and then the other; or the pivot may be arranged to shiit along the lever.

The leverf, by which rock-leverX is shifted, is pivoted to the sides of the tub at g, with its handle ranging above the top of the tu b, where it is provided with a latch, t, and a catch,j,

for setting it in threediiierent positionsviz.,

' spective bars S and U at wand they have a stud-pimp, in the side workingin a slot, q. in said bars to form stops to limit the vibration of the pawls on the said bars. The bars S and U extend from journal Joppos'ite to the pawls, and have a spring, t, bearing against their ends, which are suitably curved for working against saidsprings,theobject beingtohold'the bars Sand 1 by the friction of the springs on them, so that at each reverse of the motion of the pawls said pawls will vibrate on the pivots n to lift the retreatlng pawl out of the ratchet and depress the advancing one into it, so that when one pawl has greater throw than the otherit will advance the ratchet'more than said other pawl retreats. The bar S hasa footlever, a, connected to it by a wire, m, by which to hold pawl'lt out of action altogether for a short time whenever it maybe desired to work the rubber H one way only for quickly enter- 1. The combination, with vertically-slotted I concave and bearers N, of the rods L, springs M, tub having the side studs, P, and the slotted housings, whereby the rubber is allowed a slight vertical spring movement without shifting laterally the housings or stationary rub ber, as described.

2. The combination, with ratchet Q and rubber H, of right and left pawls, R T, bars S U, rock-lever X, and springs 27, said pawls and bars being pivoted together, and said springs acting on said bars, substantially as described.

3. The rock-lever X, having a shifting fulcrum, right and left pawls, R T, jointed conmeeting-bars S U, and the friction-springs t,

combined with ratchet Q, substantially as described.

4. The combination of shifting-lever f, clip k, and cleat m, with shifting rock-lever X, substantially as described.

5. A right and left handed ratchet mechanism consisting of ratchet Q, right and left pawls, R T, and jointedconnecting-bars S U, one of said bars connected to a foot-lever for disconnecting one of said pawls, substantially as described.
